Regarding the pattern baldness issue: You forgot the other problem, which is skull expansion, being a reason many men and some women lose their hair. As we grow older, strangely our skulls continue to grow (for whatever reason). It seems the best remedy for this at the moment is hormone replacement therapy. Males who transition to females, the skull changes shape slightly (shrinkage) along with other hormonal changes and magically the hairline returns in many cases. The real cure might be doing this to prevent unwanted physiologic changes and getting de novo hair follicles implanted if hair doesn't return. I would have no problem changing sex, but the problem is not being able to reproduce, increased cancer risk, awkward transition period and adapting to the new changes. Of course, there's the pressures of society in doing this and whether or not there will be acceptance or rejection from employers, friends and family. For those wishing to stay men and get the hair back permanently, I really don't see how this is a possibility. Heck, even Finasteride and Dutasteride are potentially feminizing and often cause permanent sexual impotence. So what to do with the hormonal issue needs to be figured out first in this battle. Most men want to stay men but how is it possible to do without eventual hair miniaturization or how to inhibit the 5AR from converting testosterone into DHT without taking away male reproductive sex abilities? Yes, so this is being done in reverse. It is the hormonal issue that needs to be worked out first and then the hair cloning if hair won't return after the hormonal issues have been worked out in individuals.
For autoimmune conditions, yes, that must be worked out first before hair will be able to survive once implanted. This alone can take years to get worked out for people if at all.
For scarring alopecia that is burnt out or happened through traumatic ends this hair cloning idea makes sense, but the skin surface has to be in good shape for the implants to take and grow.
In order words this hair cloning is going to be a cure for some people but for many others it won't be a long-term solution as the hair shrinkage and hair destruction problem will continue without other needed interventions first.
